I'll likely use the top for storing wallets, phone, and such. Whenever I troop, I almost always have Abby with me, so she can be the one to dig the stuff out.
Also, the inside of it, behind the "Grill", I'm going to add some wire mesh, some circuit boards, pips, and a fan or two, along with a few lights off to the side to give a bit of amibient lighting in it, like as if the lights were on the circuit boards or something and just part of the design. I'm not gonna have it brightly lit in there, but just enough to make out what is there, and still have it look in-universe.
